SPECIFICATION forming part of Letters Patent No. 285,085, dated September 18, 1883.

1 Application filed January 31, 1853. (No model.)

To ctZZ whom it may cancer/t:

Be it known that 1, PETER PAULY, of Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Devices for Tapping Beer Barrels, Oasks, &c.; and I do hereby declare that the .following description of my said invention, taken in connection with the accompanying sheet of drawings, forms a full, clear,

and exact specification, which will enable others skilled in the art to which it appertains to make and use the same.

My present invention has general reference to improvements in devices for tapping beer barrels, casks, &c.; and it consists, essentially,

in the novel and peculiar combination of parts and details of construction, as hereinafter first fully set forth and described, and then pointed out in the claims. In the drawings already referred to, which serve to illustrate my said invention more fully, Figure 1 is a side elevation of my improved vent. Fig. 2 isalongitudinal sectional elevation, and Fig. 3 a plan of the same. b Fig. 4 is a plan view of the under side of the vent-cap, showing the closing-valve in position. Fig. 5 is an elevation of the tapping device, showing the stop-cock in section. Fig. 6 is an elevation of the rubber bag-valve. Fig. 7 is a plan of 50 the same. Fig. 8 is a plan of the two pieces of soft rubber of which the bag is constructed. Fig. 9 is a plan of the valve, showing the passage through the same when the plates are forced apart.

Like parts are designated by corresponding letters of reference in all the figures.

In the drawings, A designates the body of my vent, having on its lower part the usual tapering shank, B, and terminating in an in-'.

0 ternally-screw-threaded socket, 0. Into this socket O is fitted a cap, D, having within its screw-threaded core a plug, H, provided with recesses b for application of a wrench and an elastic packing-ring, I, the lower part ordisk,

h, of said cap D being provided with a flapvalve, J, pivoted to ahinge-piece, Q, as clearly shown in the drawings. This hinge-piece Q is secured to the disk It by means of a screw, q, and its pintle f is surrounded by a coilspring, 3, in such manner as to cause the flapvalve J to resume a closed position with reference to the passage through the cap D whenever possible. The body A is provided with a branch, E, into which is screwed a tube, F, terminating in a nozzle, L, to which is secured the usual air-supply pipe, M. ThetubeFhas transversely an aperture fitted with a valve, 0, kept in a closed position by a spring, P. This spring is tensioned by means of a micrometer-screng ht, having in the periphery of its head certain marks designating the pressure in pounds to the square inch at which thevalve 0 will open, a pointer, 72, being provided to indicate the respective position or pressure to which the said valve 0 is set.

To the pipe or tube F, and within the body A, is secured a rubber valve or bag, K,of the usual and well-known construction, to act as an induction-valve, and to prevent the escape of air or gas from the cask S. This bagvalve, so called, is, as usually made, composed of two plates or strips of very thin soft rubber, K K, Figs. 8 and 9, cemented together along their longitudinal edges 1, Fig. 8, so as to form a bag or tube open on both ends. One of these ends is passed over the nozzle on the tube, F, and tied or otherwise se cured thereto. If pressure is exerted upon the outside of this tube, it tends to close the same, while if a fluid is forced through between the plates they will separate, as shown at 2,. Fig. 9, and thus produce a passage for the same. In this manner air forced through the hose ill, tube F, and valve K will pass into the interior of the cask into which the apparatus is inserted, while any escape of liquid from the said cask is prevented by the bag-valve closing against the same. In Fig. 2 the pipe G is shown as substantial-1y fitting into and closing the lower end of the tapering shank (B. In practice this is not the case; but the said pipe is fitted suiiiciently loose into this tapering shank to permit air being forced past said pipe G in said tapering shank B.

In operation, the vent is inserted into abarrel or cask by driving it into the proper opening in the head or a stave of said barrel. The fiap-valvc J being closed, as well as the rubber valve K and the safety-valve 0, no liquor will escape from the valve. Now, a pipe, G, is passed through the passage in the cap D and the body, of the vent into the interior of seams the cask, &c., a stop-cock,'T, Fig. 5, on the end of said pipe, in conjunction with the clastic packing-ring I, preventing the escape of liquor when said tube G is passed through the vent. hen being inserted into the vent, the pipe G will push the flap-valve J open, while as soon as said pipe is. withdrawn the spring 3 will close the same again, thus always keeping the vent closed when the tube G is not in position. Air is supplied to the cask by means of an air-forcing device (not shown) through the flexible tube M, the pipe F, and the rubber valve K. As soon as a predetermined pressure is exceeded the valve 0 will be forced open and allow the excess of air to escape, while egress of the same from the bar rel or cask is prevented by the rubber valve K. The liquor is forced from the barrel or cask through the passage 9 and other suitable connecting-pipes to the draft-faucet in the usual manner, such. draft-faucet being usually connected with the stop-cock T by means of a hose-coupling, V, and ahose or rubber pipe,U.

Having thus fully described my invention,I claim as new and desire to secure to me by Letters Patent of the United States- 1. As an improved article of manufacture, a device for tapping beer barrels, casks, &c., having the body A, provided with a branch fitted with a pipe, one end of which. is provided with a suitable valve, K, and the other with a nozzle for the attachment of ahose, said body A being provided with means for making a tight joint around the "pipe G, and with a valve for closingthe aperture through which said pipe is passed, as and forthe object specified.

2. The combination, with the bodyA, of the branch pipe F, having the safety-valve O and the airrcontrolling-valve K, said safety-valve being provided with means, substantially as described, for adjustment, as stated.

3. In a device for tapping beer barrels, 'casks, &c., the combination, with the body A, having the socket G, of the cap I), plug H, elastic packing I, and the valve J, the whole being constructed for operation substantially in the manner as and for the purpose stated.

4. The combination, with the cap D, having the disk h, .the plug H, and the elastic packing I, of the flap valve J, pivoted to thehingepiece Q, and the spiral spring 8, surrounding the pintle f, substantially as and for the ob 'jeet specified.

In testimony that I claim the foregoing as f my invention I havehereto set my hand in the presence of two subscribing witnesses.

PETER PAULY.
